How the CVE Works
CVE-2025-24067 is a heap-based buffer overflow vulnerability in Microsoft Streaming Service, allowing local privilege escalation. The flaw occurs when improperly validated input data is processed, leading to memory corruption. An attacker can craft malicious data to overflow a heap buffer, overwriting adjacent memory structures. This enables arbitrary code execution in the context of the service account, typically SYSTEM. The vulnerability stems from insufficient bounds checking during data stream handling, allowing an attacker to manipulate memory pointers and hijack execution flow.
